Definitions

  • the present application relates to a communication network comprising a novel type of call control entity, to such a call control entity, to a method of controlling such a call control entity, and to a method of using such a call control entity for migrating subscriptions in a communication network.
  • IP Internet Protocol
  • IMS IP Multimedia Subsystem
  • IMS IMS Centralized Services
  • the MSC or MSC server receives subscriber data from a Home Subscriber Server (HSS) or Home Location Register (HLR) after a UE and MSC server perform a location update procedure.
  • the subscriber data may include an optional flag. If the MSC server is enhanced for ICS it analyzes the flag value and attempts IMS registration if the flag indicates an ICS subscription, and otherwise does not attempt registration. If the MSC server is not enhanced for ICS it ignores the flag and performs regular or normal CS operation, i.e. it provides CS services as defined or standardized for CS (e.g. GSM) subscribers.
  • CS Home Subscriber Server
  • HLR Home Location Register
  • An MSC server enhanced for ICS needs to be equipped to act as a gateway to the IMS, e.g. has to provide conversion between the signalling protocols for call control on the CS side and the IMS side.
  • SR-VCC Single Radio Voice Call Continuity
  • CSFB CS Fallback
  • Multi-vendor networks are, however, the rule real mobile networks.
  • a further difficulty is that there are cases where a CS vendor may not be willing to support the above mentioned migration features, or is not able to implement them in a timeframe as required by the migration plans of the operator.
  • An object of an embodiment of the present application is to provide a generally applicable and at the same time simple mechanism for enabling migration of CS subscriptions to subscriptions to a set of services centred in an Internet Protocol based network, e.g. ICS.
  • a communication network comprises an access network and a switching control network comprising call control entities arranged for association with subscribers, where the access network is arranged for routing signalling of a given subscriber to a call control entity associated with the given subscriber.
  • the association is an attachment of the subscriber to a particular call control entity.
  • an Internet Protocol based network for providing a set of services centred in the Internet Protocol based network to one or more of the subscribers is provided.
  • the said switching control network is arranged to comprise a group of first call control entities and a group of second call control entities.
  • the first call control entities are arranged for providing call control services to subscribers having circuit switched subscriptions
  • the second call control entities are arranged for providing a gateway to connect to the Internet Protocol based network for subscribers having subscriptions to the set of services centred in said Internet Protocol based network.
  • Each of the first call control entities has a subscriber association redirector for redirecting an association of a subscriber associated with that first call control entity and having a subscription to the services centred in said Internet Protocol based network to said group of second call control entities.
  • the embodiment proposes on the one hand to employ a feature of grouping call control entities, and on the other hand to provide those of one group with the capacity to gateway to the Internet Protocol based network, and those of the other group with a mechanism for redirecting subscribers to the group with gateway functionality.
  • it is not necessary to enhance all call control entities for providing full support for services centered in the Internet Protocol based network, which saves considerable costs and makes deployment of and migration to such subscriptions to the services centered in the Internet Protocol based network far simpler.
  • FIG. 9 Further embodiments include a call control entity as described in claim 9 and a control method as described in claim 16.
  • the concepts can be applied to a method of migrating subscribers in a communication network as described above, comprising:
  • FIG. 1 shows a schematic representation of an embodiment of the invention.
  • the shown communication network comprises an access network 11, e.g. a radio access network designed to allow mobile terminals 10 access to the communication network.
  • the communication network furthermore comprises a switching control network 12 comprising call control entities 120_a, 120_b, 121_a, 121_b (e.g. MSCs or MSC servers) arranged for association with subscribers using the terminals 10, where the access network 11 is arranged for routing signalling of a given subscriber to a call control entity associated with the given subscriber.
  • the association between subscriber or terminal and call control entity can be accomplished in suitable and desirable way, e.g. by providing appropriate identifiers for the call control entities, e.g. Network Resource Identifiers (NRIs), and assigning the NRIs to the subscribers or terminals.
  • NRIs Network Resource Identifiers
  • entity refers to an element that provides the indicated functionality, and can be a physical unit, such as a network node, but can equally be constituted by a plurality of physical units acting together.
  • the communication network furthermore comprises an Internet Protocol based network 13 for providing a set of services centred in the Internet Protocol based network 13 to one or more of the subscribers.
  • Network 13 can e.g. be an IMS and the set of services may be ICS.
  • the switching control network 12 which may be part of a core network (CN), is configured to comprise a group 120 of first call control entities 120_a, 120_b and a group 121 of second call control entities 121_a, 121_b.
  • the groups may be pools as described in 3GPP TS 23.236 V9.0.0 of December 2009.
  • the first call control entities 120_a, 120_b are arranged for providing call control services to subscribers having circuit switched subscriptions.
  • they may be MSCs or MSC servers arranged to provide regular CS services, e.g. call waiting, call forwarding, etc.
  • the second call control entities 121_a, 121_b are arranged for providing a gateway to connect to the Internet Protocol based network 13 for subscribers having subscriptions to the set of services centred in said Internet Protocol based network 13.
  • the set of services may be similar or overlapping to the CS services, e.g. also include call waiting and forwarding, but may also include other, new services and functions.
  • the set of services may be Multimedia Telephone (MMTel) Services.
  • MMTel Multimedia Telephone
  • the group of second call control entities 121_a, 121_b may comprise MSCs or MSC servers enhanced to support IMS but also retaining the capability of providing CS services, but also may comprise dedicated gateway entities that do not provide CS services.
  • Figure 1 is naturally only an illustrative example, and each group or pool 120, 121 may have more or fewer entities in it, i.e. a group may contain one or more call control entities.
  • each first call control entity 120_a, 120_b has a subscriber association redirector for redirecting an association of a subscriber associated with each first call control entity 120_a, 120_b and having a subscription to the services centred in said Internet Protocol based network 13 to the group 121 of second call control entities 121_a, 121_b.
  • the determination of what kind of subscription is present can e.g. be done with the help of an appropriate data base, such as a HSS or HLR 14, which may be queried by a call control entity and/or which may set corresponding parameters in the call control entities.
  • an appropriate data base such as a HSS or HLR 14, which may be queried by a call control entity and/or which may set corresponding parameters in the call control entities.
  • the subscriber association redirector may be arranged for detecting subscriptions to the set of services centred in said Internet Protocol based network 13 on the basis of a subscription marker set by a subscription register entity like HLR 14.
  • the marker is the ICS flag described e.g. in TS 23.292 V.9.4.0 in section 7.2.1.1.
  • an embodiment of the present invention proposes to use the an appropriate marker (like e.g.
  • the ICS flag not just as an information element that leads to registration to network 13 (e.g. IMS registration) in fully enhanced MSC servers, but to the triggering of a redirection in MSC servers that are only slightly modified with respect to normal MSC servers.
  • the slight modification can e.g. be implemented by a simple patch, thus avoiding the costly, complicated and time consuming full enhancement of all MSC servers at once and at the same time.
  • the redirecting to the second group 121 can be done in any suitable or desirable way.
  • the association can be redirected to a member of the group, e.g. by using an individual member identifier, or the association can just generally be redirected to the group, e.g. by using a general group identifier. Both examples lead to a redirecting to the group.
  • the subscriber association redirector may be arranged for redirecting the association by assigning a new Temporary Mobile Subscriber Identity. Then the redirector may be arranged for redirecting the association by one or both of:
  • the subscriber association redirector may equally be arranged for redirecting the association of the subscriber having a subscription to said services centred in said Internet Protocol based network by sending a reroute command to the access network, e.g. a Multi-Operator Core Network (MOCN) Reroute Command as specified e.g. by TS 23.251 V. 9.1.0 of December 2009.
  • a reroute command e.g. a Multi-Operator Core Network (MOCN) Reroute Command as specified e.g. by TS 23.251 V. 9.1.0 of December 2009.
  • MOCN Multi-Operator Core Network
  • the concept of grouping (e.g. pooling of CN nodes) of call control entities is combined with the concept of subscriber or terminal redirection in the context of CS call control and service provision and service provision by an IP based network (e.g. IMS), in order to provide a simple but very effective mechanism for allowing migration of users from CS service subscriptions to subscriptions for services of the IP based network.
  • IP based network e.g. IMS
  • the method of migrating subscribers in a communication network comprises grouping the switching control network into a group of first call control entities and a group of second call control entities, the first call control entities are arranged for providing call control services to subscribers having circuit switched subscriptions, and the second call control entities are arranged for providing a gateway to connect to said Internet Protocol based network for subscribers having subscriptions to services of said Internet Protocol based network, providing in each first call control entity a subscriber association redirector for redirecting an association of a subscriber associated with each first call control entity and having a subscription to the set of services centred in said Internet Protocol based network to the group of second call control entities, and step by step or gradually changing predetermined groups of said circuit switched subscriptions to subscriptions to the set of services centred in the Internet Protocol based network.
  • the step by step changing of predetermined groups means that an operator can provide a migration plan of gradually changing the subscriptions of more and more subscribers, but does not need to initially fully upgrade the CS network in such a way that all call control entities are fully enhanced to support IMS. It is sufficient to only have some call control entities that provide the gateway functionality to the IMS, which are grouped in the second group 121, and to provide the simple redirection mechanism in the other call control entities, which are grouped in the first group 121.
  • This redirection mechanism can e.g. be implemented by a simple patch, i.e. can be rapidly implemented at low cost and with no impact on the ongoing operation.
  • FIG. 2 shows a schematic representation of a call control entity arranged to provide the above described functionality.
  • the call control entity 20 comprises known elements, such as a communication part 21 for exchanging data and signals with other network entities, a processor 22 for controlling the entity and processing data and information, and a storage part 23 for holding data and software.
  • the processor 22 can e.g. be a programmable processor.
  • the call control entity comprises a call controller 221 for providing call control services to subscribers having circuit switched subscriptions.
  • the call controller 221 can be provided as hardware, software, or any suitable combination of hardware. In the example of Figure 2 , controller 221 is constituted by appropriate computer code parts executed in processor 22.
  • the call control entity furthermore comprises a subscriber association redirector 222 for redirecting an association of a subscriber associated with the call control entity and having a subscription to the set of services centred in said Internet Protocol based network 13 to the group 121 of call control entities arranged for providing a gateway to connect to the Internet Protocol based network 13.
  • the association redirector 222 can be provided as hardware, software, or any suitable combination of hardware. In the example of Figure 2 , redirector 222 is constituted by appropriate computer code parts executed in processor 22.
  • FIG. 3 shows a flow chart of a method embodiment of the present invention.
  • a method of controlling a call control entity of a communication network as described above is shown.
  • the method comprises controlling (S33) call control entity to provide call control services to subscribers having circuit switched subscriptions, and redirecting (S32) an association of a subscriber associated with the call control entity and having a subscription to the set of services centred in said Internet Protocol based network to a group of call control entities arranged for providing a gateway to connect to said Internet Protocol based network.
  • the procedure determines in step S31 whether a subscriber associated with the entity has an ICS subscription (e.g. by checking the above mentioned marker), and if yes, redirecting the association to the second group 121, and if no, providing CS network based services.
  • the network shown in Fig. 4 comprises MSC nodes 41, supporting a set of subscriber services consisting of standardized CS services, and possibly an additional number of proprietary services. These MSC nodes 41 are not upgraded with support for ICS, i.e. are not fully enhanced. When migrating the subscribers to IMS, the standardized CS services are e.g. replaced by MMTel services. Typically, the same implementation of proprietary services in IMS is not supported.
  • the basic concept of the embodiment is to add ICS support to the network by adding new nodes supporting ICS.
  • These nodes are here called MAGCF (Mobile Access Gateway Controller Function) 42 and do not need to execute any CS based services, but only to grant a subscriber access to the IMS service domain also when roaming in 2G/3G radio access areas. So before the subscriber is migrated to IMS, he is served by the MSC nodes 41 and the MSC based services. After the migration to IMS, he is served by the MAGCF nodes 42, giving him access to IMS.
  • MAGCF Mobile Access Gateway Controller Function
  • the embodiment combines MSC nodes 41 and MAGCF nodes 42 in a pool configuration.
  • the RAN nodes 44 (BSC and/or RNC) are connected to all MSC and MAGCF nodes 41, 43.
  • the MSC nodes 41 and MAGCF nodes 42 are combined into two sub-pools, respectively 40 and 43.
  • MSC and MAGCF nodes have individual NRI identifier, as indicated in Fig. 4 , which allows the RAN nodes 44 to route subscribers always to the same controlling node.
  • the sub-pool of MSC nodes and the sub-pool of MAGCF codes have different, unique Null-NRI identifiers.
  • the starting point of the migration of CS subscribers to IMS can be to build a common pool of MSC and MAGCF nodes. However, all subscribers remain in the MSC nodes sub-pool, which are upgraded by a simple patch 51 to support this invention.
  • the migration of CS subscriber to IMS is done by adding the ICS subscription to the subscriber profile in HLR 45, see 59.
  • the HLR 45 updates the MSC node 41 where the subscriber is located (Step 1), i.e. the MSC node with which the subscriber is associated.
  • the VLR (not shown) is updated with the changed data.
  • the new logic in the MSC 41 detects that the subscriber now has an ICS subscription in his profile, so he is ported to IMS, see 53 and 54.
  • the MSC 41 assigns a new NRI value to the subscriber.
  • This NRI value points to one of the MAGCF nodes and the subscribers can be assigned to all existing MAGCF nodes in a load sharing manner.
  • the MSC has a record of all NRIs of members of pool 43, and assigns the NRIs in a round-robin fashion.
  • the location update is acknowledged containing a non-broadcast LAI/RAI (step 5), which causes the terminal to immediately do a new location update.
  • step 6 the terminal uses the new TMSI with the new NRI value, which causes the RAN node to forward this location update to the MAGCF node 42 owning this NRI (55 and step 7).
  • the MAGCF 42 receiving this location update request registers the subscriber by informing the HLR 45, downloading the subscriber data (step 8), and acknowledging to the terminal (step 9).
  • the HLR 45 cancels the old registration in the MSC 41 (step 10).
  • the same mechanism could be used to port subscribers back to MSC.
  • This is shown in Fig. 6 .
  • the MAGCF 42 is informed and notices the change.
  • the subscriber can be pushed back into the MSC.
  • the MAGCFs do not need to be able to provide CS based services, i.e. they can be implemented to exclusively act as gateways to the IMS, because the provisioning of CS based services can be accomplished by redirection.
  • Another option is to use two unique Null-NRI values per sub-pool 20 and 43. It is known to use multiple Null-NRI values in shared network to distribute traffic between two operators.
  • the RAN node 44 checks the NRI value to decide the routing towards the pool.
  • a Null-NRI value means that no pool node has been selected, and the load distribution function of the RAN node, for example the Non Access Stratum (NAS) Node selection function of TS 23.236 V. 9.0.0, is used select a new pool node for the subscriber, see 74.
  • MAGCF 42 sets its own NRI (5 in the example, see 75) for the TMSI, in order to provide a unique association.
  • NAS Non Access Stratum
  • a reroute command as shown in Fig. 8 , e.g. the Multi-Operator Core Network (MOCN) Reroute Command from MSC to RNC to indicate in to the RNC to redirect the subscriber.
  • MOCN Multi-Operator Core Network
  • the MSC 41 will check the ICS subscription (82), and if the subscriber is to be ported to IMS, the MSC 41 will at the next location update order the RAN node 44 to redirect the location update to the MAGCF 42.
  • the migration of CS subscribers to IMS is done by adding the ICS subscription to the subscriber profile in HLR 45 (see 59).
  • the HLR 45 updates the MSC node 41 where the subscriber is located (Step 1).
  • the VLR is updated with the changed data.
  • the new logic in the MSC 41 detects that the subscriber now has an ICS subscription in his profile, see 82, so he is ported to IMS.
  • the MSC 41 returns a Reroute Command to the RAN node 44 (step 4), including also the International Mobile Subscriber Identity (IMSI) of the subscriber.
  • the Reroute Command causes the RAN node 44 to send the Location Update request to the MAGCF (83 and step 5), which now includes the IMSI.
  • the MAGCF 42 receiving this location update request registers the subscriber by informing the HLR 45, downloading the subscriber data (step 6), and allocates a TMSI with its own NRI (84 and step 7).
